Chapter 21: Problem 1

Name three of the four peptides for which proenkephalin is the precursor.

Short Answer

Expert verified
Question: Name three peptides derived from the precursor molecule, proenkephalin. Answer: Met-enkephalin, Leu-enkephalin, and Peptide E.

Step by step solution

01

Understand Proenkephalin

Proenkephalin is a protein precursor that is processed to generate smaller active peptides, which belong to the family of endogenous opioid peptides. These peptides function in pain relief and other physiological responses.
02

Identify the Four Peptides Derived from Proenkephalin

Proenkephalin is processed to produce four main peptides: (1) Met-enkephalin, (2) Leu-enkephalin, (3) Peptide E, and (4) Peptide F.
03

Name Three of the Four Peptides

Now that we have identified the peptides produced from proenkephalin, we can name three of them: (1) Met-enkephalin, (2) Leu-enkephalin, and (3) Peptide E.
